Application filed September 1, 1927. Serial No. 216,972. 1

structed to be pendently supported by said conveyer in position, forhaving the bales conveniently deposited thereon from hand trucks,- andhaving thereon means to engage the bales or other articles supportedthereon and secure them against inadvertent displacement while beingtransported, but.

which are readily removable to facilitate unloading of the bales whendesired.

.With the above and other objects in view that will hereinafter appear,theinvention further resides in the novel details of construction,combination'and arrangement of parts, all of which will be first fullydescribed in the following detailed description, then beparticularlyipointed out in the appended claims, reference beinghad tothe accompanying drawings, in which Figure 1 is a perspective viewillustrating the inventionin use. 7

Figure 2 is an end view, the loading of a cotton bale onto the traybeing indicated in dotted lines.

, Figure 3 is a face view of the tray, the pivoted arms being removed.

Figure 4: is a horizontal section taken just above the base of the trayand looking to- Ward the base.

Figure 5 is a detail vertical cross section of the supporting anglewitha hanger bar attached thereto.

Figures 6 and 7 are diagrammatic end views illustrating modified formsof bale securing means.

In the drawings in which likenumerals of reference indicate like partsin all ofv the figures, 1 generally designates a. traveling conveyer'ofany approved type adapted to travel along guide trackways fordistributing bales of cotton or similar loads.

Hanger bars 2 are pivotally or pendently connected at 3 to .theconveyer,and, attheir lower extremities, are hooked under an angle ironsupporting bar 4 as indicated'at 5 and are secured. to that bar byrivets or other suitable securing means as at' 6.

End standards '7 are secured as at 8 to the ends of thesupporting bar 4to depend therefrom and are suitably braced adjacent their connectionwith the said bar by the angle braces9.

At their lower ends the standards 7 are i bent downwardly and outwardlyas at 10 and cooperate with similarly bent members 11, which are securedthereto as at 12, in supporting a rectangular open tray 13, the lowerextremities of the portions 10 and 1?. being secured to the tray cornersas at let.

To provide for the desired strength of the tray 13 and for desiredeconomy of manu facture the same is preferably constructed of angle ironbent to form an open rectangle as is clearly indicated in Figures 1 and4 of the drawings. The corners of the tray are suitably braced andreinforced by the corner plates 15, and to suitably close the openbottom portion of the tray'and' also to brace the same, cross bars 16are secured across the base flanges'of the "angles at spaced intervalsandl. 1

Cleats 17 fOIHlGd'Of short lengths of angle iron are secured as at 18 tothe opposite faces of the vertical flange portion of the supportingangle 4 at opposite sides thereof and with their extended facesopposedin spaced relation, see Figures 1 and 3. Each cooperating pair ofextended flanges of the cleats are apertured to receive a pivot pin 19upon which is pivoted a loadsecuring arm 20 branched or forked as at 21'toward its free end to form a'pairof arm portions each equipped with aninwardlyand upwardly directed sharp nose 22 adapted to bite into andassist inso curely holding a load upon a tray.

In this disclosure I have illustrated four suchsecuring arms arranged inopposed pairs as is clearly illustrated in Figures 1 and 2 of thedrawings; In practice I have found this equipment quite practical but itshould be understood that a greater or;

lesser number of arm pairs may be employed to suit the needs of anyparticular use of the invention. 1

The extended fianges of the cleats 17 also serve .to mount a stop pin 23which limits the downwardniovement, or movement .of the arms 20 towardeach other, as indicated by the dotted lines to the left of thecenter ofFigure 2.

By referring to Figure 2 of the drawings it will be observed that whenit is desired to load a tray with a bale'or bales of cotton or any othersimilar load, the arms 20 at one side are raised in any'suitable manneras indicated by the dotted lines to the right of the as indicated inFigures 3 center of Figure 2, while the arms at the the tray is beingaccomplished the hook ends 22 of the opposed arms, because of theirupward and inward direction of pro ection, will automatically'bite intothe bale and limit its movement beyond the desired substantiallyvertical position illustrated. This loading of the bale or bales beingcompleted the formerly raised arms are lowered to cause the sharp noses22 thereof to bite into the opposed side oi the bale and cooperate withthe previously engaged arm ends in securely holding the load to positionagainst inadvertent displacement during travel of the conveyer.

I When it is desired to remove the load it is, of course, only necessaryto lift the securing lugs at a convenient side of the tray to releasethe bale or bales at that side and render removal thereof possible.

In Figures 6 and 7 of the drawings I have illustrated slightly modifiedmeans for securing the bales to position upon the tray. In Figure 6, 24:indicates a fixed abutment secured as at 25 to the supporting angle 4 toproject into position for forming a fixed or positive abutment at asuitable position i V at one side of the tray. The usual pivotedsecuringarms 2022 are employed at the opposite side of the tray andcooperate with the said fixed abutment in securing the load to positionupon the tray and in providing adjustable receiving space foraccommodating varied sizes of loads.

In F igure 7 the same fixed abutment is illustrated at one side of thetray but a modified means of adjustably. securing the load at the otherside of the tray is provided. In this form 01 the invention a simplelink chain 26 may be employed and may be ad justably connected to thesecuring hooks 27 carried by the standards 7. In this form when a baleis mounted on the tray 13 with one side thereof againstthe abutment 2 1one linkof the chain may be slipped over the hook on one end standardand drawn tightly 7 around the, side of the bale and a suitable link atthe other end of the chain slipped over the hook mounted on the otherend standard. By providing this chain and hook securing means loads ofvarious sizes may be accommodated by utilizing various links insecuringthe' load to position. V

From the foregoing description, taken in connection with theaccompanying dravings, it is thought that the novel details ofconstruction, the manner of use and the ad vantages oi' my inventionwill be readily apparentto those skilled in the art to which it relates.
